With its release, we got the music video for the album’s title track. It’s a relatively simple video that features Kesha singing “Rainbow” in a recording studio.

In the letter, Kesha recounts her time “alone and scared in rehab for an eating disorder” in 2014. At first the facility she was staying in wouldn’t give her access to instruments, but she talked them into giving her an hour a day with a keyboard. “Writing songs is the only way I know how to process things,” she explains.

“The whole album idea and tour and everything, came from me crying and singing and playing and dreaming until my hour was up and they took the keyboard away again. Every day I would just cry and play that song because I knew I had to get through that incredibly hard time.”
